AC Operating Conditions
(TA = 0 to 70 °C, Voltage referenced to VSS = 0V)
Notes: 1. VID is the magnitude of the difference between the input level on CK and the input on CK.
2. The value of VIX is expected to equal 0.5*VDDQ of the transmitting device and must track variations in the DC level of the
same.
